Re: 1993 Lowe 185 wiring diagram
Welcome to iboats.
Sorry t5o say but you are on your own, they just don't have those available like cars do, they don't make enough boats to cover the cost of making one.
The factory may have had one at one time but maybe not.
Normally they farm those out and the people come in lay out the harness and then go make it and they come in labeled for whatever boat and noone in the factory ever sees a diagram.
Check the console good for fuses, there shoudl be a fuse block some where and if that sin't it check grounds, most electrical problems can be traced to a bad ground.
Good luck.
